BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Nemesia, botanically known as Nemesia caerulea×Nemesia strumosa and hereinafter referred to by the name ‘Kirine-13’.

The new Nemesia is a product of a planned breeding program conducted by the Inventor in Tochigi, Japan. The objective of the breeding program is to create new Nemesia cultivars with good vigor and attractive flower coloration.

The new Nemesia originated from a cross-pollination made by the Inventor in March, 2004 in Tochigi, Japan of the Nemesia caerulea cultivar White Wings, not patented, as the female, or seed, parent with the Nemesia strumosa cultivar Nebula Orange, not patented, as the male, or pollen, parent. The new Nemesia was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in Tochigi, Japan in September, 2004.

Asexual reproduction of the new Nemesia by terminal cuttings in a controlled environment in Tochigi, Japan since October, 2004, has shown that the unique features of this new Nemesia are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Kirine-13 has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature, daylength and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Kirine-13’. These characteristics in combination distinguish ‘Kirine-13’ as a new and distinct cultivar of Nemesia:

-   -   1. Upright, somewhat outwardly spreading and mounded growth         habit.     -   2. Freely branching and flowering plant habit.     -   3. Large cherry red-colored flowers.     -   4. Relatively tolerant to high temperatures.     -   5. Good garden performance.

Plants of the new Nemesia differ from plants of the female parent, the cultivar White Wings, in the following characteristics:

-   -   1. Plants of the new Nemesia are larger than plants of the         cultivar White Wings.     -   2. Plants of the new Nemesia have larger flowers than plants of         the cultivar White Wings.     -   3. Plants of the new Nemesia and the cultivar White Wings differ         in flower color as plants of the cultivar White Wings have         white-colored flowers.

Plants of the new Nemesia differ from plants of the male parent, the cultivar Nebula Orange, in the following characteristics:

-   -   1. Plants of the new Nemesia are larger than plants of the         cultivar Nebula Orange.     -   2. Flowers of plants of the new Nemesia are fragrant whereas         flowers of plants of the cultivar Nebula Orange are not         fragrant.     -   3. Plants of the new Nemesia and the cultivar Nebula Orange         differ in flower color as plants of the cultivar Nebula Orange         have orange-colored flowers.     -   4. Plants of the new Nemesia are more tolerant to high         temperatures than plants of the cultivar Nebula Orange.

Plants of the new Nemesia differ from plants of the cultivars Kirine-9, disclosed in a U.S. Plant patent application Ser. No. 11/489,224; Kirine-12, disclosed in a U.S. Plant patent application Ser. No. 11/489,223; Kirine-14, disclosed in a U.S. Plant patent application Ser. No. 11/489,164; and Kirine-15,disclosed in a U.S. Plant patent application Ser. No. 11/489,404, primarily in flower color.

Plants of the new Nemesia can be compared to plants of the cultivar Intraired, disclosed in U.S. Plant patent application Ser. No. 11/174,979. In side-by-side comparisons conducted by the Inventor in Tochigi, Japan, plants of the new Nemesia differed from plants of the cultivar Intraired in the following characteristics:

-   -   1. Plants of the new Nemesia were more mounded than plants of         the cultivar Intraired.     -   2. Plants of the new Nemesia had larger leaves and flowers than         plants of the cultivar Intraired.     -   3. Plants of the new Nemesia and the cultivar Intraired differed         in flower color.     -   4. Plants of the new Nemesia were more high temperature tolerant         than plants of the cultivar Intraired.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Nemesia, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Nemesia.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used. Plants used for the aforementioned photograph and following description were grown under conditions which closely approximate commercial production conditions during the late spring in a polyethylene-covered greenhouse in Santa Paula, Calif. for about 10 to 13 weeks in 15-cm containers. During the production of the plants, day temperatures ranged from 16° to 27° C., night temperatures ranged from 7° to 15° C. and light levels ranged from 5,000 to 7,000 foot-candles. Plants were pinched one time about four weeks after planting.
